Each conference has their own exit bylaws. AAC is 27 months and 10 mill - yup, you read that right. Mountain West is 12-15 months I believe - not sure on exact cash.

That's not to say that negotiations can't be made, but I think the difficulty of AAC teams getting out is something often overlooked and a reason that CSU might be much more of a viable option than people think if the conference wants teams by 2017 to go along with their return to having a conference championship game. Plus, CSU could easily overtake CU in Colorado as the top team if in the Big 12 - because CU freaking sucks.

Idea / prediction:

Big 12 announces BYU and CSU to join in 2017 and Cinci and Houston to follow in 2018.
